Students learn their lessons in class. In class, teachers teach them. Students sit in the classroom listening to the teacher. Is this the only way for students to learn? Of course not. There is another way to learn. That is, students can teach themselves. For example, if you cannot remember anything when you are doing your homework, you can look through（浏览） your book to find the answer. This is a way to teach yourself. And it's not a difficult thing. We can do it at any place and at any time.

    How to teach yourself? The first thing you must do is to read. Read something interesting. The second is that you must ask yourself questions. Many clever students often do this. The questions are about something you don't understand or you want to know more about. You can write down these questions. The third is to answer the questions yourself by thinking hard, by reading the texts or other books, and sometimes by asking other people. These are the ways of teaching yourself. And if you do these things for a long time, you can succeed（成功）in your study.

Animals

    Corona viruses are common in animals. Sometimes, animals get infected (感染的) with these viruses which may then spread to human beings. To protect yourself, you should not visit live animal markets or have direct contact with wild animals. Stay away from raw meat, animal organs and other undercooked animal products.

    When an infectious pet was found in Hong Kong, some may wonder if one can get virus from their pets. Until today, there is no evidence that a dog, cat or any pet can transmit (传播) COVID-19. Please do not kill or give up pets!

Touching surface with virus

    Studies suggest that COVID-19 virus may stay on surfaces for a few hours or up to several days. However, the number may change under different conditions such as type of surface, temperature or the environment.

    If you think a surface may be infected, clean it with ethyl alcohol (酒精). After touching it, clean your hands with alcohol or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

Package (包裹)

    Before delivering to your home, a package has been moved, travelled, and exposed to different conditions and temperature. Therefore, the possibility of being infectious because of your package from COVID-19-reported areas is rather low. There is no need to send your package back.

Smoking

    An article posted on Wechat recently says that cigarette can protect smokers from COVID-19 and thus make cigarettes sell very well. It is an online rumor (谣言)! As has been known, smoking harms people's health. It weakens the immune system and worsens diabetes and blood pressure. No smoking is still a must!

Transportation

    According to Feng Luzhao, an expert from the Chinese Center for Disease Control and Prevention, the major routes of transmission are still through respiratory droplets and direct contact. In order to protect yourself in underground station, wearing a mask and keeping your hands clean are good ways. People are also encouraged to use a personal transportation card or pay for the ticket via an app. After taking public transportation, washing hands is necessary.

Lin Wenqian is a girl student. When she was on a busy bus last month, she felt someone touching her. She was so afraid.

Zhou Bin, 12, is a boy. He likes to chat on the Internet. But once a stranger said lots of dirty things to him.Zhou was so surprised!

What can students do when this kind of thing happens? Here is some advice from some teachers and students:

Don't be afraid. Ask him or her to stop at once. If he or she doesn't listen, try to turn to others around you and call for help.

Keep calm. Be serious and keep a cool face. Say you don't like it and show you are angry.

If there is no one around, use clever ways. If you only shout or fight to make them angry, it could make things worse! They may take your life. Find excuses (借口) to run away. Say things like you are waiting for your parents or you want to go to the washroom.
